The first observation is that genes are actually stored in two locations. The first location acts as a cache where all active genes are kept. The second location is a more denser storage area where inactive genes are kept. The second observation is that all genes are stored as http://web.mit.edu/newsoffice/2009/3d-genome.html ">fractal globules which allows genes that are used together to be adjacent to each other when folded, even though they may be far apart when unfolded.Link to Original Source
